• Interventions: Drug: TQB2029 injection

• Registration Number: NCT06700395
• Lead Sponsor: Chia Tai Tianqing Pharmaceutical Group Nanjing Shunxin Pharmaceutical Co., Ltd.

Brief Summary

This is a study to evaluate the maximum tolerated dose (MTD), dose limiting toxicity (DLT), occurrence of all adverse events (AEs) and serious adverse events (SAEs), pharmacokinetic parameters, pharmacodynamic parameters, immunogenicity, and anti-tumor effects of TQB2029 for injection in Chinese adult subjects with multiple myeloma. The study is divided into Phase Ia and Ib, Phase Ia: dose escalation phase, to evaluate the safety and tolerability of TQB2029 for injection, and determining DLT and MTD; Phase Ib: Dose extension phase, to evaluate the effectiveness of TQB2029 for injection in subjects with multiple myeloma.

Arm && Interventions

Group	Intervention	Description

Number of patients with adverse events (AEs) and serious adverse events (SAEs)	Up to 18 months	Assessed by the National Cancer Institute Common Terminology Criteria for adverse events (NCI-CTCAE) v5.0.
Dose Limiting Toxicities (DLT)	During the first 28 days	DLT refers to any of the following events in the first administration of TQB2029 for injection to the end of the first treatment cycle (C1D28) that the investigator and the sponsor consider to be related to the treatment of TQB2029 for injection.
Maximum tolerated dose (MTD)	Up to 18 months	After the experiment is completed, sequential regression is used to determine the maximum tolerated dose (MTD). Specifically, calculate the toxicity rate of each dose group and select the dose closest to the target toxicity rate as MTD.
Recommended Phase II Dose (RP2D)	Up to 18 months	Determine RP2D based on target toxicity rates for each dose group

Secondary Outcome Measures

Name	Time	Method
Elimination half-life (to be used in one-or non- compartmental model) (t1/2)	The first and second treatment cycle: 0 hours, 2 hours, 6 hours, 24 hours, 48 hours, 72 hours, 96 hours, 120 hours, 168 hours after dosing on the first day, 0 hours on the 15th day, and 0 hours on the 22nd day.	t1/2 is time it takes for the blood concentration of TQB2029 or metabolite(s) to drop by half.
Maximum (peak) plasma drug concentration (Cmax)	The first and second treatment cycle: 0 hours, 2 hours, 6 hours, 24 hours, 48 hours, 72 hours, 96 hours, 120 hours, 168 hours after dosing on the first day, 0 hours on the 15th day, and 0 hours on the 22nd day.	Cmax is the maximum plasma concentration of TQB2029 or metabolite(s).
Area under the plasma concentration-time curve from time zero to time t (AUC0-t)	The first and second treatment cycle: 0 hours, 2 hours, 6 hours, 24 hours, 48 hours, 72 hours, 96 hours, 120 hours, 168 hours after dosing on the first day, 0 hours on the 15th day, and 0 hours on the 22nd day.
